Sam Posted October 8, 2012 Share Posted October 8, 2012 I need to generate a speciation diagrams for Al+++ ,Ca++,Mg++ ,Fe+++ and Fe++ as a function of pH. To see how speciation diagrams are generated in React I tried the example on pages 214 and 215 of the text: Geochemical and Biogeochemical Reaction Modeling , 2nd edition , by Graig M. Bethke typing in the folowing commands as in the book: decouple UO2++ 10 mmolal Na+ 10 mmolal Cl- 1 mmolal UO2++ swap H3PO4 for HPO4-- 1 mmolal H3PO4 pH = 2 slide pH = 10 precip = off go The program ends successfully but when I ask it to plot the results I do not get the diagram which is Figure 14.12 on page page 215 of the text.Instead React gives me a diagram (generated by Gtplot) that has the vertical axis labelled "components in fluid (moles)" and a horizontal axis labeled "Rxn progress" the plotted results are completely differrent ,of course ,from that shown in figure 14.12 in the text. Please help,as I am already behind schedule on generating these speciation diagrams. Quote Link to comment Share on other sites More sharing options...
